尝试这样的事情，除去最后3行父我不能删除最后一排...

SELECT ppse.SUBORDINATE_POSITION_ID child_position_id 
      ,ppse.PARENT_POSITION_ID manger_position_id 
      ,b.person_id 
FROM per_pos_structure_elements_v ppse 
    ,APPS.xxkpc_hr_personnel_v2_mv b 
WHERE b.position_id(+) = ppse.SUBORDINATE_POSITION_ID 
AND b.type(+) = 'KPC Employee' 
AND ppse.POS_STRUCTURE_VERSION_ID =64 
AND ppse.PARENT_POSITION_ID=12493 
AND 
(b.person_id!=null OR 
ppse.SUBORDINATE_POSITION_ID in 
      (SELECT SUBORDINATE_POSITION_ID from per_pos_structure_elements_v))

它不与PARENT_POSITION_ID = 12504一起使用，它将删除12493的行，该行是子级的父级 – 2012-07-29 08:29:36

尝试从最后一条语句中删除NOT。显示如下... ppse.SUBORDINATE_POSITION_ID in （从per_pos_structure_elements_v中选择SUBORDINATE_POSITION_ID）） – 2012-07-29 08:37:02
